I recently spun up a centos 6.0 box and decided to go threw the strokes of setting it up as a bonified webserver. The installation was easy opening the correct ports was not. A quick summery of what I did:

Step 1: installed vsftpsd with sudo yum install vsftd

Step 2: I modified the vsftpd.conf file to include some settings -

first I made sure that anonymous connections weren't allowed anonymous_enable=NO

then I set ftp users to be "jailed" to there home directory and pointed to a file of users that I do not want to "jail" (I also created an empty chroot_list in the specified location) chroot_local_user=YES chroot_list_enable=YES chroot_list_file=/etc/vsftpd/chroot_list

this locked down vsftpd to use predictable passive ports pasv_min_port=3000 pasv_max_port=3050

if you were given a default conf file you probably can just scroll through it to uncomment out these lines.

Step 3: Once that was finished I fired up vsftpd with sudo service vsftpd start

Step 4: Now I had to punch a whole into my firewall to open the ports that vsftpd uses. I first opened up vsftpd's default listening port(21) with sudo iptables -I INPUT -p tcp --dport 21 -j ACCEPT then I had to open the passive ports that I configured in the conf file(3000 to 3050) with sudo -I iptables -I INPUT -p tcp --dport 3000:3050 -j ACCEPT

Step 5: By default my iptables was set to not save on restart, you can modify this in /etc/sysconfig/iptables-config by setting the option IPTABLES_SAVE_ON_RESTART="no" to yes, I do not do this in case I mess up my fire wall settings I can just restart with sudo service iptables restart. But since I haven't messed anything up (yet) i need to save my current iptables with sudo service iptables save. Now if I restart my box or restart my iptables these ports will still be open.

Step 6: Now I needed to create a user to test with so I created a user sudo useradd -g users testftp then sudo passwd testftp, then used the password ftp. Fired up my favorite ftp client dropped in my credentials and was jailed to my home directory. Good Job for the night.

Happy MOVEYOURDOMAIN day!

So I've decided to finally leave godaddy for all my domain registrations. I knew they were evil I just never had the motivation to transfer, but some of the deals that are being offered today are too good to pass up.

I would recommend namecheap with the code SOPASUCKS. They seem to be the cheapest for strictly domain transfers.

There are some others offering discounts on hosting etc. if you just google "moveyourdomainday" you'll find some more information.

I've censored the following, in protest of a bill that gives any corporation and the US government the power to censor the internet--a bill that could pass THIS WEEK. To see the uncensored text, and to stop internet censorship, visit: http://americancensorship.org/posts/13637/uncensor

So I just went through a pain staking process of setting up a local MAMP stack on a mac lion machine. And I just wanted to post about two pit falls that I came across.

1. When I installed mysql using brew, it placed the mysql.sock file into /tmp/mysql.sock not the default /var/mysql/mysql.sock. First I found/verified where the mysql.sock file is with “locate mysql.sock” then I made a symbolic link between /var/mysql/mysql.sock to /tmp/mysql.sock with “ln -s /tmp/mysql.sock /var/mysql/mysql.sock”

A colleague of mine found a programming challenge; out of a triangle of numbers, start at the top and then find the greater number out of the two below it. and then give the total, rinse/repeat Example:

5 9 6 4 6 8 7 0 1 5

Answer: 27

I found this interesting so I gave it a whack in python

import os #initialize dir = os.path.dirname(__file__) fileName = os.path.join(dir, 'triangle.txt') triangle = open(fileName, 'r') p = 0 total = 0 #for each numbers line in triangle for numbers in triangle:     #strip out line delimiters   numbers = numbers.rstrip('\r\n')   numbers = numbers.split(' ')     #find the last index of numbers   numNumbers = len(numbers) - 1     #pop it off if its blank from stripping the line delimiters   if (numbers[numNumbers] == ''):     numbers.pop(numNumbers)     #if it isn't a blank line   if numNumbers > 0:     #it there is only 1 number use it     if numNumbers == 1:       #if so set position to 0       p = 0       #largest is in position 0       largest = numbers[p]     else:       #check if the greater number is in the set position       #if not move the position 1 place and use that number       if long(numbers[p]) > long(numbers[p+1]):         largest = numbers[p]       else:         p += 1         largest = numbers[p]     #running total     total += long(largest) print total
